[pianotech] disc sander

[Mike Spalding]

William,

I converted my 5" handheld random orbital sander from PSA to hook & 
loop.  While I am generally pleased and have no intention of going back, 
I have found that the discs have a limit on how many times they can be 
installed/removed before the loops fail and they don't stick any more.  
It keeps me from using discs whose abrasive is worn out and dull <G>.
